DINGWALL, UK

Guests can take the ghost tour, which explores the building's many passageways and staircases, but don't stray too far as the halls are said to be haunted by the infamous Green Lady of Tulloch.

1886 CRESCENT HOTEL AND SPA

EUREKA SPRINGS, ARKANSAS, US

Originally opened as a luxury resort at the end of the 19th century, the Crescent Hotel fell into disrepair before becoming a college and conservatory for young women and then a hospital and health resort clinic run by a quack doctor, Norman Baker, who duped desperate patients with fake cancer cures.

Today, the turbulent history of what is billed as America's most haunted hotel lives on in the form of its many "permanent residents".

Among them are a stonemason who fell to his death during construction of the hotel, cancer patients from Baker's hospital days and the resident ghost cat.

The hotel offers a ghost tour, which includes a visit to its chilling morgue, then a spa so guests can chill after their thrill.

Q STATION

SYDNEY, AUSTRALIA

Until its closure in 1972, new arrivals who were suspected of bringing infectious diseases to Australia were isolated for 40 days in the North Head Quarantine Station. Smallpox, cholera and the bubonic plague made the quarantine centre the final resting place of more than 500 of its forced residents.

Today, it has been converted into a visitor centre and heritage accommodation, but it is still known as Australia's most haunted spot and has been featured on TV shows and in horror movies. Apart from ghost tours, Q Station also offers informative historical tours and outdoor activities such as kayaking and snorkeling.
